Question

Define:

Condensation point.

Answer 1

• Matters normally exist in three states viz. solid, liquid and gas.
• The states of matters can be interchanged with the release or absorption of heat.
• State change can be understood from the flow chart given below.
• $\mathrm{Solid}\underset{\mathrm{Freezing}}{\overset{\mathrm{Melting}}{\rightleftharpoons }}\mathrm{Liquid}\underset{\mathrm{Condensation}}{\overset{\mathrm{Boiling}}{\rightleftharpoons }}\mathrm{Gas}$
• Condensation is the state change of gas into a liquid.

Condensation point- Condensation point is the temperature at which a gas changes into its liquid state.

• It is different for different matters.
• For example, water has a condensation point of $100°\mathrm{C}$, which is also its boiling point.
• At $100°\mathrm{C}$ or below that temperature water vapor changes into water.
